The times I've thought of a girl as being "clingy" usually involved them telling me way more often than they should things such as "I miss you," "I wish I could see you," "I love you," etc. Saying these things every now and then is not a bad thing whatsoever. It's nice to know that your SO cares about you and wants to be around you. It gets clingy when these things are each said 2, 3, or 4 times a day, or just at an obnoxiously high rate.

This is within a relationship, though. Outside of a relationship it would seem clingy if a girl showed attachment traits well before it was time. Such as second date she starts talking about getting married. That's a bit extreme but you catch my drift.
